Low-quality power supply hits the consumer's pocket very hard. Refrigerators and microwaves, televisions and computers are an integral part of our home. But they are all powered by AC and depend on a stable voltage for normal operation. The equipment is not cheap at all and repair does not guarantee trouble-free operation in the future.
The mains voltage depends on many factors. It is not always the fault of the electricity supplier. Deterioration of networks, remoteness from the substation, presence of energy-intensive consumers in the neighborhood ... There are many factors, but the result is one - voltage drop or fluctuations. As a result - breakdown and expensive repairs or complete failure of household appliances. The stabilization of the power supply of devices can save the situation, and modern technologies will help us in this.
